Most soft magnets are Fe-based materials, such as metallic iron, silicon–iron alloys or iron phosphides. However, nickel–iron alloys are the most representative examples of this type of materials. NiFe alloys are commonly known as Permalloys and the name usually refers to a composition close...
However, these strategies cannot be the whole story behind coercivity. For example, in the iron–nickel system, a sharp drop in coercivity occurs at the Permalloy composition, at whichκ1 = −161Jm−3. Tuning the magnetocrystalline anisotropy constant to zero in iron-nickel alloys in ...
